GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 603,136, dated April 26, 1898. Application filed February 3 1897. herial No. 621,860. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. GORDON, of Valley View, in the county of Cooke and State of Texas, have invented a new and Improved Gang-Plow, of which the following is a full, clear, and exact description.

The invention relates to an improvement in that class of gang-plows which employ disks turning in the soil and serving to form the furrows therein.

The invention consists in certain peculiar features of construction and combinations of parts, as will be fully described hereinafter and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation on the line 1 1 of Fig. 2. Fig. 2 is a plan view. Fig. 2 is a detail perspective of a part to be hereinafter described. Fig. 3 is a sectional view on the line 3 3 of Fig. 2. Fig. 4 is a detail section taken through one of the disks and means for mounting the same. Fig. 5 is an elevation of one of the disks separated from the means for mounting it and showing the conical trunnion or plug of the disk in end ele vation. Fig. 6 is a rear elevation of the means for mounting the guide-wheel. Fig. 7 is a fragmentary perspective of a key which I employ, and Fig. 8 is a partial section of a portion of the frame.

The frame has two longitudinal beams 9, joined at their front ends by a cross-beam 10 and having their rear portions connected by a diagonal beam 11. The beams 9 are hollow and receive in their square interiors the squared front ends 12 of the spindles 13, (for details of which see Fig. 8 and for the assembled position of which see the dotted lines in Fig. 2.) A diagonal tie-rod 14 runs through the beam ll-and through the ends 12 of the spindles 13. The beams 9 have their rear ends out of transverse alinement, and the spindles 13 are of different lengths so that the right-hand spindle will terminate at a point forward of the termination of thelefthand spindle.

Bolted to the under side of the beams 9 and running transverselybetween the two are two plates 15, the opposite ends of which carry ratcheted segments 16 and have the hand-levers 17 fulcrumed thereon at the points 18. In rigid connection with the lower end of each lever 17 is a rearwardlyprojecting arm 19, to which the spindles 20 of the gage-wheels 21 are respectively connected. By these means the gage-wheel 21 may be raised or lowered with reference to the frame of the machine and the depth at which the disks operate in the ground may be regulated. Each gage-wheel 21 is provided with a ballastdisk 54, which is removably held thereto by clips 55. These ballast-disks serve to weight the wheels and cause them to hold the plowdisks in proper engagement with the ground. If the condition of the soil does not require such downward pressure, the disks 34 may be readily removed and for the moment dispensed with. A spring-arm 22 projects upwardly and rearwardly from the rear plate 15 and carries a seat 23, whereon the driver of the plow may rest.

Each spindle 13 is round at the portions of the spindles that are rearward of the beams 9. Mounted on each spindle 13 and directly adjacent to the rear ends of the beams 9 are the means for carrying the disks. The disks are two in number and are duplicates of each other, as well as are the means for mounting them. Each of these means consists in a sleeve 24, having a vertical bolt 25 passing through transversely-alined slots in the upper and lower sides of the sleeve. The bolts 25 are held rigidly in openings 26 of the spindles 13, (for one of which openings see Fig. 8.) By these means the sleeve 24 may be turned on the spindles 13. Each spindle 13 is provided on its lower side with a square kcyway 27. Each sleeve 24 is provided at the lower portion of its bore with a square keyway 28. Sliding in these keyways is a key 29. (See Fig. 7.) This key has a cross-sectional form characterized by two squares diagonally disposed with reference to each other. When the lower of these squares is at the left side of the vertical center of its spindle 13, the corresponding sleeve 24 will occupy the position shown in Fig. 4. When the lower of the squares defined by the crosssectional form of the key 29 is at the left of the center of the corresponding spindle 13, the sleeve 24 will be held in a different posiof vertically-alined arms 51.

tion with reference to the spindle 13, such position throwing the axis of the disk-to down- Ward inclination, and thus making it possible to regulate the manner in which the disk engages the earth.

Each sleeve 24 carries atits bottom a transversely disposed and tapering socket 30, through which the conical trunnion or plug 31 extends. The plug 31 has an annular flange 32, embracing a similar projection 33, carried by the socket 30. By these means the bearing of the plug 31 with the socket is kept free from grit or other impurities. A concavo-convex disk 34, with a centrally-recessed hub-block 35, is secured to the plug 31 by a bolt 36, running through the socket and through the block, the block 35 receiving the left-hand end of the plug 31 within the recess in the block. Each sleeve 24 has a lug 37 projecting upwardly therefrom and carrying an overhanging arm. 38, to which a scraper 39 is fixed. The scrapers 39 project downwardlyand respectively engage the eoncave sides of the disks 33 at points near the pleripheries thereof, wherebyto keep thedisks c ear.

The rear end of the left-hand spindle 13 projects beyond its sleeve 24 and carries an approximately-segmental block 40. The curved side of the block 40 is provided with ratchet-teeth adapted to coact with similar teeth ona triangular block 41. A transverse bolt 42 passes through the blocks 40 :and 41 and through the rear portion of the left-hand spindle 13, by which means the parts 40 and 41 are rigidly connected with'their corresponding spindle. The block 41, as shown in Fig. 2, has a longitudinal slot to permit'the-block 41 to be adjusted on the bolt 42. The blocks 40 and 41 carry the guide-wheel 43 of the machine, which guide-wheel is journaled on a diagonal spindle 44, carried by a plate 45, through which a pivot-bolt 46 passes to the plate 47. The left-hand portion of the plate 45 has a series of openings 48, with which the adj usting-bolt 49 may have connection. The bolt 49 passes to-the plate 47, and by means of the bolts 46 and 49 and the openings 48 the plate 45 may be adjusted on the plate 47 to regulatethe inclination of the spindle 44. The plate 47 is carried by a bracket 50, the forward portion of whiohis formed with two pairs The pairs of arms5'1 respectively embrace the left-hand portion of the plate 40 and the plate 41. The arms5l, whichembrace the block 40, have a bolt 52.passin g through them and through the block, While the arms 51, which embrace the block 41, have a bolt 52" passing through them and running vertically against the outer face of the block 41. The bracket is thus mounted to swing or wag freely on a vertical pivot wheel 43. l The axis of the guide-wheel accordingly, therefore, is adjustable both on a vertical and horizontal pivot.

The plow is adapted to be drawn by horses through the medium of a tongue 53, projecting from the cross-beams 10. In operation the attendant, through the manipulation of the levers 17, regulates the depth at which the disks 34 enter the ground. The disks are thus adjusted in a manner to suit the condition and character of the soil which is being tilled, as will be understood. The staggered position of the guide-wheel 43 causes the wheel to evenly support the rear portion of the frame and at the same time to run in line laterally removed from the line in which the disks 34 run and therefore not to interfere with the work of the disks on the soil.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The'combination of a spindle having a keyway, a member to turn on the spindleand also having a keyway, and a key with two diagonally-disposed parts respectively capable of running in the keyways of the spindle and of the said member whereby to hold the said member in two positions with reference to the spindle, substantially as described.
